Just out of curiosity have you or anyone you know made a third hole to put the blue air tube with the fill line back on the WF modules? I was thinking about trying but just wanted to put out some feelers? I put a hold on my res for one, it's the third hole on the pic. I might use it to feed a 1/4" air pump tube to air stone or something inside of the res. Have a good one!

GH WATERFARM USERS: SIMPLE RECIRCULATING SYSTEM Ok so I was at my hydro store yesterday and the BRAIN pulls out this kit from GH that makes your w/f set recirculating!! Ordinarily this isn't very exciting news EXCEPT...... Get ready.......:jointsmile: It uses an air pump and drip ring set up to move the water through the system. You do NOT NEED A WATER PUMP! Let me repeat that part: YOU DO NOT NEED A WATER PUMP. IT RUNS OFF A BASIC AIR PUMP. Rating: 5
